Subject[PATCH v5 2/4] dt-bindings: mfd: Document the Xylon LogiCVC multi-function device
Date
The LogiCVC is a display engine which also exposes GPIO functionality.
For this reason, it is described as a multi-function device that is expected
to provide register access to its children nodes for gpio and display.
